EXHAUST-WHISTLE.

Specification of Letters Patent.

Fatented Jan. 2, 19T?.

Application med september 2, 1913. Ysenta No. 787,607.

To all whom t may concern Be it known that I, Mon'roN G. BUNNELL, a citizen of the United States of America, and resident of Chicago, Cook county,Illinois, have invented a certain new and useful Improvement in Exhaust-Whistles, of which the following is a specification.

My invention relates to chime whistles which are blown by the exhaust from motor boats or automobile engines.

Generally stated, the object of my invention is to providea novel and highly efficient exhaust whistle of this kind.

A special object is to provide an exhaust whistle in which the opening of the exhaust valve not only throws the exhaust into the atmosphere, but also serves to render the whistle inoperative. and to prevent dust and dirt from entering the whistle while not in use, through vthe medium of a rod which slides endwise within the whistle, and which forms a medium ot' connection between the exhaust valve and some element of the sound producing means.

It is also an object to provide, in an exhaust whistle of this particular character, an automatic valve for vclosing communication Lietween the exhaust and the sound producing means, when the exhaust valve is opened, and which will open automatically when the said exhaust valve is closed.

It is also an object to provide certain details and features of improvement tending to increase the generaly eiciency and desirability of an exhaust whistle of this particular character. n

To the foregoingand other useful ends my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings, Figure l is a longitudinal section of an exhaust whistle embodying the principles of my invention, showing the same in condition to prevent blowing of the whistle, and to discharge the exhaust into the atmosphere. Fig. 2'is a detail longitudinal section on line 2v2 in Fig. Vl. Fig. 3 is a cross section on line 3-3 in Fig. l. Fig. 4 is a cross section on line 4 4 in Fig. 1. Fig. 5 is a view similar to Fig. l showing another form of my invention. Fig. 6 is a detail longitudinal section on line 6 6 in Fig. 5. Fig. 7 is a cross section on line 7-7 in Fig. 5.

As thus shown, my invention comprises a stationary member A having an exhaust inlet a connected with the exhaust of the engine. Said member also has an outlet a1 for the exhaust, controlled by an outwardly opening valve B, which latter is held normally open by a spring whereby the whistle is normally inoperative. Discharge openings a2 are provided in the side of the body opposite the said outlet al, of any suitable number, and connection between these openings and the exhaust is controlled by a valve C, which is normally closed, and which is iixed on the longitudinally disposed rod c of the whistle. This rod hadits end arranged to engage a roller 721 on the exhaust valve, whereby said rod is moved endwise to open said valve C when the valve B is opened. y

The tubes D are disposed parallel around the rod c and are united by a sleeve d that slides over the tube ell, which latter is ixed in the member A, forming a guide for said rod. A set screw Z2 is inserted through the sleeve Z to engage the tube all, whereby the tubes D can be adjusted toward and away from the member A, in order to bring their ends in proper position relative to the slots a2, whereby the proper tone is produced. The shell or sleeve E incloses the said tubes D, and slides thereon to close the openings between the member A Vand the ends of the tubes D, thus preventing the entrance of dustand dirt. This element E is secured to the rod c, whereby the whistle is Y'rendered operative when the valve B is closed. A spring F connects the outer closed end ot' the shell E with the tube d1, thus serving to pull the shell toward the member A, to close the openings a7, when the valve B is opened after blowing the whistle. For this purpose, it will be understood, the said spring is fastened at its end in any suitable manner.

In Figs. 5 to 7 the construction is substantially the same as previously shown and described. In this case, however, the exhaust valve G is fixed on the end of the rod g, and the spring g1 is interposed between the valve g2 and the wall of the member H, as shown. Also, the sleeve or shell I is open at both ends, and has its outer end secured by a spider z' to the said rod, which latter has an eye J for connection with the operating means. The tubes K are like those previously described, and the exhaust escapes from the slots ,7a. against Vthe end edges of said tubes, when the valve .G is closed and the valve g2 opened; and at such time the spring g1 is compressed and the shell I is away frein the member H, whereby the whistle is in condition to operate.

As shown, the tubes D and the shell E are square in cross section, but it will be understood that this is not essential, and that tubes of any shapezin cross section can be used if necessary or desirable. As shown, a key cl3 is interposed between the sleeve Z and tube Z1 to prevent rotation of the structurev about the rod. l Any other suitable means, however, can be employed for this purpose, and witha view to maintaining the ends .of the tubes D in proper relation to the slots CL2, without interfering with the adjustment vof the tubes D toward and from said slots. lt is also obvious that the sleeve or :shell l shown in Figs. 5 and 7, can be connected with the rod g in any suitable or desired manner. This can be changed or modified as circumstances may require, without departing from the spirit of my invention. Again it is obvious that the arrangement oi the spring g1 can be changed or varied if necessary or desired, without interfering with: the characteristic mode of operation of my invention. For example, the parts can be so proportioned and formed that the-.said spring may be vof greater length than shown.

I do not limit myself to the exact construction shown and described'.

`What I claim as my invention is:

l.. An exhaust whistle-structure comprising a stationary member adapted to be connected with the exhaust, having an exhaust outletand `a liuid discharge opening, an element having endvvise motion toward and awayfroin said openingfservi-ng to control communication between the atmosphere and Copies of this patent may be obtained. for

the interior of the structure, said element being mounted on said member, an out-V vardly opening valve for said outlet, a connection between saidelement and valve, including a rod mounted to slide enwise in saidmember, and means to control the valve androd, a device inside of said element for receiving the exhaust from said opening, thereby to produce the sound, means for adjusting said device toward and away 'from said opening. y

2. in exhaust whistle comprising a hollow member having exhaust inlet and outlet openings, a passage through which the exhaust escapes to operate the whistle, an outwardlyA opening external valve? 'for said outlet, and means serving to prevent the exhaust from escaping through Vsaid passage when the said outlet is open, but not when the valve is closed, saidV outlet being :dis:

posed between' said inlet and said valve, to-V gether with a'spring for normally holding said valve in open position. v

3. An exhaust whistle comprising` a hollow member having exhaust' inlet and outlet openings, apassage through which the exhaust escapes to operate the whistle, an outwardly opening external valve for saidouti let, and means serving to prevent the exlia-ust from escaping through said passage lwhen the said outlet is open, but not when the valve is closed, said outlet -being dis posed between said inlet and said valve, said means comprising a wall wi-thin said member.
